Title: Improvements in Prepayment Attachments for Gas Meters.
Inventor: DREW WILLIAM THOMAS
Filed: 1903-03-03
Granted: 1903-04-16
Abstract: 4936. Drew, W. T, March 3. Gas meters.-Prepayment attachments, for. The coin is dropped through a slit 15, Fig. 4, into a slot 14 in a drum 7 rotated by means of a handle 10. The coin projects into the slot 16 of the outer drum 8, and carries it round till the coin has passed the guard plate 17, when it drops out. The drum 8 is geared to a cage consisting of two end plates 24, 25, Fig. 7, and connecting-bars 26 on which slides a nut 27 engaging with the screw 23. As the drum 8 is rotated, the nut is fed along the screw, and the pin 29 acts on an arm 30 and rocks a shaft 31, on which is a slotted arm 32 which engages the valve-rod and opens the valve. The ordinary counting-shaft 37 is geared by a worm 41 and wheel 42 to a shaft 43, on the squared end of which is a movable wheel 44 which is geared to the spur-wheel 49 fast on the screw 23. The ordinary motion of the shaft 37 thus rotates the screw 23 and feeds the nut 27 back again, and so closes the valve and shuts off the gas. An ordinary counting- apparatus registers the number of times the barrel 8 is rotated, and thus indicates the number of coins received, and a sliding bar indicates the position of the nut 27 aud consequently the amount of gas still to be used before another coin need be inserted.

Granted: 1903-10-29
Abstract: 16,349. Cress, L. H. July 24. Medicines. - Relates to the preparation of a substance called cetyl - guaiacyl, " cetiacol," or " palmiacol," apparently pyrocatechin-methyl-cetyl ether, which is insoluble in water, soluble in alcohol, ether, chloroform, &c., melts at 15‹ C., decomposes at its boiling-point, and has similar medicinal properties to guaiacol but does not irritate the gastro-intestinal or other parts. It is stated to be applicable for the treatment of tuberculosis &c. Sodium or potassium alcoholate is first prepared by adding modium to cooled alcohol, then guaiacol is added, forming sodium or potassium methyl-pyrocatechin, and the whole is poured upon spermaceti oil at a temperature of 80‹ C. and allowed to digest. The contents of the jar are next mixed with glycerine. On standing, the cetyl-guaiacyl collects at the top. The lower layer is siphoned away and the remainder cooled to solidify the cetyl-guaiacyl, which is then easily removed and purified by partial liquefaction. An excess of spermaceti should be used as guaiacol is difficult to separate from the product. Creosote may be used in place of guaiacol. The lower layer containing glycerine, alcohol, and either sodium or potassium palmitate, is treated with perchloride of iron. On heating, ferric palmitate separates out as a soft magma which is removed and used medicinally. Alcohol is then separated from the remainder, and the glycerine which remains is purified by distillation i= vacuo.

Title: Improvements in Milking Machines.
Inventor: SIM WILLIAM
Filed: 1903-09-01
Granted: 1904-04-21
Abstract: 18,875. Sim, W. Sept. 1. Cow-milkers.-Relates to a machine in which the teats are periodically pressed against rubber pads and the udder shaken by means of pistons operated by air pressure. Fig. 1 shows a cross-section of the " milker," between the tongue 6 and pad 16 of which the teat is inserted. The tongue 6 is pivoted to the rod 5 of a piston 3 by a pin the ends of which slide in grooves 8. The travel of the upper part of the tongue is limited by a pin 11 coming into contact with adjustable stops 13. The removable pad 16 and the tongue 6 are curved so as to cause a slight doubling at the neck of the teat. A fixed or detachable ring 18 guides the teat into the tube 1, and may hold a rubber sheath for it. A cylinder having a dome-shaped flange 25 is adjustably secured to a slotted holder 21, Fig. 3, and encloses a piston which moves up and down and causes the "bumper" 26 to shake the udder. The holder 21 is secured to the cow by means of straps attached to the cross-bar 28, the udder resting upon the flange 25. The milkers are adjusted along the bent arms 20, which are fixed at any required angle. The pistons of the bumpers and milkers are moved by means of an air pump operated by a beam on a rocking shaft, a safetyvalve being provided between each pair of cows. The pump is an ordinary valveless air pump provided with an air inlet pipe so that air may enter from the outside of the building at the beginning of the inward stroke. The inward stroke compresses the air and forces the tongues 6 against the teats, and the outward stroke relieves the pressure on the teats. Instead of connecting the milkers with the milk bucket by means of rubber tubes, a funnel may be pressed up against them by means of a spring coiled round it and bearing against a movable stop on it and against the milk can. Arms may be secured to the bumper to form a holder for the udder, and bumpers may be arranged to act on the sides of the udder.

Granted: 1905-01-12
Abstract: 24,275. Wilkinson, J. Jan. 4, [date applied for under Patents Act, A.D. 1901]. Steam &c. turbines. - Governing- mechanism for elastic-fluid turbines is shown in Fig. 3. The turbine nozzles 6 are controlled by valves 10 actuated by pistons 11. The pistons are exposed underneath to boiler steam and on the top to the downward pressure of a series of graduated springs 12 and to a governed fluid pressure. A tubular valve or nozzle 22 is connected to a governor so that its position varies according to the speed of the engine. This valve is connected to a steam pipe and is adapted to direct a current of steam into a pipe 27 leading to the valve-controlling pistons or into a pipe 28 leading to the turbine wheel. This fluctuation of pressure causes the valves to open according to the load on the turbine. By means of an eccentric device 43, the tubular valve is oscillated so that a pulsating action is produced. In a modification, a rotary valve or nozzle 48 is used, as shown in plan in Fig. 2. This valve has a central fluid channel leading to radial outflow channels, and the steam is directed into flared openings 55 at different levels leading to the valveoperating pistons and turbine wheel respectively. The nozzle valves may be operated by compound pistons 85, Fig. 5, working in chambers which are connected in series by passages 82 and are connected to a high-pressure pipe at 92, to an exhaust pipe at 84, and to the governor-controlled valve at 89.
